Edgar claims the kingship in early 1095.

His older brother Edmund sides with Donald, presumably in return for an appanage and acknowledgment as the heir of the aging and son-less Donald.

Edgar receives limited support from William II as Duncan had before him; however, the English king is occupied with a revolt led by Robert de Mowbray, Earl of Northumbria, who appears to have had the support of Donald and Edmund.

Rufus campaigns in northern England for much of 1095, and during this time Edgar gains control only of Lothian.

A charter issued at Durham at this time names Edgar "... son of Máel Coluim King of Scots ... possessing the whole land of Lothian and the kingship of the Scots by the gift of my lord William, king of the English, and by paternal heritage."

Edgar's claims have the support of his brothers Alexander and David—Ethelred is Abbot of Dunkeld, and Edmund is divided from his siblings by his support of Donald—and his uncle Edgar Ætheling as these witness the charter at Durham.
